and only so much thereof is disclosed herein as is necessary to illustrate my invention in its embodiment therein.

While the machine of the present invention is capable of a wide range of uses, it will be suflicient if I first give a general and brief description of one of such uses and describe briefly how it is carried out; thereafter describing in detail the construction and operation of the machine in connection with the particular use set forth, by way of example.

The example taken involves the use of a ledger sheet L, shown in Fig. 11, and a bill or primary work sheet B such as is illustrated in Fig. 12. It

will be observed that the ledger sheet is ruled with a series of vertical columns a, b, c, d, e, f, g, h, i, 7', each under an appropriate caption, such as Line numbers, State, City", Total tax, Paid in full, Date, Refunds, Remarks. A

cross line entry in the different columns, or such of them as may be required, and on a single numbered cross line is made for each bill. Instead of having a bill sheet of a width equal to the ledger sheet, on which these various items are entered I propose to employ a comparatively narrow bill sheet B and enter the same items or some of them thereon in a vertically disposed arrangement as shown in Fig. 12, and to make each of such entries simultaneously on both the bill and ledger sheets. By my invention I provide simple and effective means by which this may be accomplished. Such means include a bill or primary work sheet carrying auxiliary carriage mounted on the platen carriage for stepby-step letter spacing movement therewith and for independent shifting movement along the same to bring the bill sheet into register with another part or vertical column on the ledger sheet for the next entry, and so on with suc- 4'0 cessive entries. Each entry on the bill sheet is duplicated through an interposed carbon sheet on the ledger sheet. Work sheet feeding means are employed to advance the bill sheet independently of the platen and ledger sheet after each item entered, so that the diflerent items of a bill will appear in a horizontal line across the ledger sheet but will be vertically disposed on the bill sheet.

With the foregoing preliminary description I 5 will now describe in detailthe present embodiament of my invention in the hereinbefore mentioned Remington machine.

In said machine a platen carriage carries a cylindrical platen 2 and is mounted on bearing 5 rollers 3 to travel over the top plate 4 of the machine from side-to-side thereof, the bearing rollers being supported in the grooved ways in fixed guide rails 5 and 6 secured to the top plate of the machine. The carriage is spring impelled in the direction of its feed under control of the usual carriage escapement mechanism (not shown) and the platen is actuated in the usual manner to efi'ect a line spacing operation thereof.

Two curved paper deflectors l and B are arranged beneath the platen, being maintained spaced apart to provide a channel 9 between them. A work sheet, say, a comparatively wide ledger sheet L is introduced into the machine from the rear of the platen and into the space between the platen and the deflector I, being carried around in front of the platen and beneath the usual feed rollers l0 located above the printing line, if said feed rollers are td be used, as will hereinafter more clearly appear. Whethor or not said feed rollers iii are to be used will depend somewhat on the character of the ledger sheet employed, and whether there are sumcient side margins on the ledger sheet, not to be filled in, to enable the feed rollers HI to coact with said margins of the sheet. Of course if the feed rollers II) are not to be used they may be moved forward to and held in the ineffective position, shown in Fig. 4, by merely shifting the usual finger piece Ill forward from the Fig. 1 position. If the rollers H! are to be used, then in any set-up they will be adjusted laterally to coact with the side margins only of the relatively wide sheet L, so that in no event will the feed rollers I ll interfere with a lateral shifting of the bill sheet B to overlap any desired portion of the ledger sheet L, as will hereinafter more clearly appear.

Outside of ledger sheet, and substantially coextensive in size therewith, is a carbon sheet C by which a manifold copy of the items written on the bill sheet may be produced on the ledger sheet.

Both the ledger and carbon sheets, in the present instance, pass beneath paper feed rollers which bear on the top of the platen. In said prior Remington machines said feed rollers were carried by a bail. In the present construction this bail is omitted and feed rollers ll, preferably two in number, are mounted in the usual manner for adjustment along a rod I2 that constitutes a cross bar connecting two side plates l3 of a supporting frame, which will be hereinafter more fully-described. The weight of this supporting frame and the parts carried thereby eflectively holds the feed rollers ll against the platen or the sheets C and L thereon.

The outermost or primary bill or work sheet B is introduced rearward from in front of the platen with its lower end foremost into the open mouth of the unobstructed channel 9 provided between the two paper deflectors l and 8. In thus introducing the lower end of the bill sheet into the channel 9 the usual front deflector M may be brought to the Fig. 4 position and aid in the introduction of the sheet, the usual printing line indicator I5 having at this time been moved to the ineffective position.

As indicated in Fig. 2 there are two side edge guides or gages IS on an auxiliary carriage, said gages being spaced apart to correspond to the width of the bill sheet and between which the bill sheet is received and by which it is guided. Each of these side guides is formed as a part of a supporting plate I! on which a bill sheet is adapted to rest and be supported. As shown in Fig. 9 each member I6I| has rearwardly directed perforated ears I! il each ear il also having fixed thereto an inwardly extending hub 20 tapped to receive a set screw 2!. The auxiliary carriage by which the parts |6I| are carried comprises end plates is and I9 rigidly united by suitable cross bars or rods 22 and 23. The cross rod 23 passes through the perforations in the ears il whereas the cross rod 22 passes through the perforations and hubs 20 of the ears I'l In this manner the members l6l 1 are supported on and may be adjusted along the cross rods 22 and 23 and may be spaced apart to coact with bill sheets B of various widths. A threading in of the screws 2! causes them to engage the rod 22 and hold the members l6-l I in their adjusted positions.

The auxiliary carriage is supported on a cross bar 24 that in normal position is arranged above the platen and parallel with the axis thereof.

Said cross bar extends throughout the length of the carriage and is fixed at its ends by screws 25 to the end plates |3 of the supporting frame and may be regarded as a part thereof. In the 5 present instance the auxiliary carriage is supported to travel along the cross bar 24 by four grooved rollers 26 which coact with the opposite V-shaped edges of the bar. As shown in Fig. a pair of said rollers are supported on two 10 inwardly extending ears 21 formed, in the present instance, integral with each end plate |3 of the auxiliary carriage. Each ear 21 has a spindle 28 detachably secured thereto and projecting forwardly therefrom. The forward end of each is spindle is provided with bearings for anti-friction balls 29 that provide a ball bearing for the associated bearing roller 26. This has proved to be an efficacious manner of connecting the bearing rollers to the auxiliary carriage since the comparatively long line of supporting connections between each roller and the associated side plates of the auxiliary carriage affords a slight resiliency that enables said carriage to move freely along the cross bar 24 notwithstanding lack of absolute trueness of the bar, which ordinarily might cause the auxiliary carriage to stick or bind thereon. The auxiliary carriage is, nevertheless, guided with sufficient accuracy, and with a freedom that enables it to be quickly posi- 30 tioned by hand to any desired selected point along the platen carriage.

Means are provided on the auxiliary carriage for holding a bill sheet and advancing it in a line-feed direction independently of the platen and the ledger sheet thereon. Such means, as

they are embodied in the machine in thepresent instance, will now be described.

Paper feed rollers 30 are fixedly, though adjustably. secured to a driving shaft 3| by screws 40 32. A loosening of each screw 32 enables the associated feed roller 33 to be adjusted along the shaft 3| and secured in its adjusted position on said shaft, thus affording such an adjustment of the feed rollers as may be required for bill 45 sheets of different widths.

The driving shaft 3| is supported in bearing openings in the lower ends of two pivoted arms or plates 33 and 34. The arm 33 is pivoted at its upper end on the reduced portion 35 of a 50 shouldered screw bolt 36 secured to the end plate I8 of the auxiliary carriage, as shown in Fig. 2.

An inwardly projecting pin 31 on the arm 33 forms an abutment for one end 38 (see Fig. 4) of a spring that is coiled around the enlarged portion of the screw bolt 36 and bears at its other end 39 against a pin 40 projecting in from the end plate IS. The force of this spring is exerted to move the shaft 3| rearwardly and maintain the feed rollers 30 in effective position against 60 the bill sheet and against a suitable support therefor. In the present instance such support is represented by a series of paper feed rollers 4| mounted on and adjustable along a rock shaft 42 mounted in the end plates l3 and IQ of the auxiliary carriage. The power of the spring 38-49 is exerted to maintain the feed rollers 30 against the rollers 4|, with a bill sheet interposed between them.

70 A corresponding spring coacts in a like mannet with the arm or plate 34 to attain the same ends, so that both ends of the shaft 3| will be spring-pressed rearward. Thus, it will be seen from an inspection of Fig. 3 that a spring is 75 coiled around a peripherally grooved head 43 fixed to the end plate I9 of the auxiliary carriage. One end or arm 44 of this spring bears against a pin 45 projecting from said end plate l3, whereas the other end or arm 46 of the spring bears against a pin 41 projecting from the arm or plate 34.

I have provided manually controlled means by which the feed rollers 30 on the auxiliary carriage may be shifted at will to and from effective position and may be held or retained in the incifective position out of contactive engagement with the bill sheet B.

In the present instance these last mentioned means comprise the rock shaft 42 on which the feed rollers 4| are free to turn. This rock shaft has an actuating crank arm 48 secured thereto at one end and which terminates in a finger piece 49. A second crank arm 50 also is secured to the rock shaft 42 and is pivoted at 5| to a link 52. This link in turn is pivoted to the arm 34 on a headed extension 53 of the pin 41 on the opposite side of the side plate l9, as shown in Figs. 1 and 2. The crank arm 50 has an extension or stop 54 that projects from the free end thereof and is adapted to coact with a stop pin 55 on the link 52 when the link and arm are brought into substantially a straight line position, as shown in Figs. 3 and 4. This occurs when the feed rollers 30 are shifted off to releasing position. At this time the spring 44, 46 is exerting a force endwise on the members 52 and 50, which force is resisted by the shaft 42 and tends to hold the members 52 and 50 and the parts controlled thereby in the shifted position with the feed rollers 30 released.

The extension 53 on the plate 34 also constitutes a pivotal support on which a gear wheel 56 is mounted to turn. This gear meshes with a pinion 51 secured to one end of the shaft 3| on which the feed rollers 30 are fixed. Motion is thus transmitted to the shaft 3| and feed rollers 3|! to feed a bill sheet B when said feed rollers press against the bill sheet or against the rollers 4| by which the sheet is supported.

A line spacing advance of a bill sheet B is effected by transmitting an intermittent step-bystep rotative movement to the gear 56. In the present'instance this is brought about by manually controlled means carried wholly by the auxiliary carriage and consisting of a gear 58 that meshes with the gear 56 and is riveted to a line spacing wheel 55 to turn therewith. These members 53 and 59 are mounted on and fixed to turn with a stub shaft 60 supported in the head 43 which is in the nature of a bearing bushing secured to the end plate I9. The shaft Bil is prolonged to the right at El beyond the hub 59* of the line spacing wheel, where it has a finger wheel 32 secured thereto. This finger wheel may be availed of to turn the gear 53 and, through the intermediate train of connections, turn the feed rollers 30. The line spacing devices for intermittently turning the wheel 53 and thus turn ing the feed rollers 3|] comprise a line spacing pawl 63 pivoted at 64 on a pawl carrier 65 mounted to turn freely on the hub 59' of the line spacing wheel, and therefore around the pivotal axis of the latter. The engaging nose of the line spacing pawl 63 normally rests on the curved face 66 of a. shield 61 that determines at what point in the throw of the line spacing pawl it will engage the line spacing wheel, thereby de termining how much movement shall be given the line spacing wheel at each actuation of the pawl 83. To vary this amount the shield is mounted on the end plate I! for adjustment in a circular path around the pivotal center of the wheel 59 by screw and slot connections 88 and 68 respectively. A spring 89 is coiled around a 5 pin ill on the pawl carrier 55 and is anchored at one end and bears down at its free end I59 on the line spacing pawl 63 thus tending to force the engaging end of the latter towards the line spacing wheel and against the outer face of the shield 66.

The pawl carrier 65 is intermittently actuated or rocked around its pivotal center 80 by the following means.

A link ll is pivoted at one end, as at I2, to the pawl carrier 65. The other end of this link is pivoted at 13 to a lever arm 14 which in turn is pivoted at 15 on the end plate 18 of the auxiliary carriage. A spring 16 is coiled around the pivot 15 of the lever 14 and is connected at one end to a pin 11 on said lever and at the other end to a pin 18 on the end plate l9. The force of this spring is exerted to return the lever I4 and the parts connected therewith to the normal position, shown in Fig. l, where they are arrested by -35 the pin 18 coacting with a stop pin 19 projecting from the outer face of the end plate l9, as shown in Figs. 1 and 2. The free end of the lever 14 carries a finger piece 80 by which it may be depressed. This will result in swinging the pawl carrier 65 in an anti-clockwise direction, as the parts are shown in Fig. 1, during which move ment the link ll approaches a straight-line position with reference to the lever 14. The effect of this is to shift the end of the line spacing pawl 63 ofi its shield 66 and permit it to engage the line spacing wheel and transmit movement to the feed rollers 30. Such motion continues until the back (i3 of the free end of the pawl coacts with a stop pin 8| (Fig. 1) projecting from the end plate I9. This tends to wedge the pawl into more tenacious engagement with the line spacing wheel and arrest it and the pawl and prevent overthrow under the manual actuation of the parts.

It will be understood that the arm 34, by which the ars 56 and 51 are carried, is pivoted on the stub shaft 60 on which the gear 58 and line spacing wheel 58 are mounted. It follows therefore that the arm 34 may receive a pivotal movement with the arm 33 to control the movement of the feed rollers 38 into and out of effective position without altering the relation of the line spacing wheel 59, and gears 58, 5B and 51 relatively one to another, saidygears remaining constantly in mesh and effective whether the feed rollers be in the effective Fig. 1 position or in the ineffective Figs. 2 and 3 position. A spring-pressed roller detent 59 coacts with the line spacing wheel 58 and is mounted on the arm 34 to swing therewith.

The usual line spacing mechanism including a line spacing wheel 82 (Fig. 1) is employed for the platen 2 to advance the ledger sheet L and carbon sheet C but such mechanism has nothing whatever to do with the bill sheet B which is under independent control for line spacing advance movement by the feed rollers 30 actuated by the finger piece 80 or the finger wheel 62.

The end plate I9 has an upwardly extending To P rtion 83 that constitutes a finger piece situated conveniently adjacent to finger piece all, so that the operator with one hand may grasp the finger piece 83 to shift the auxiliary carriage along to any desired position relatively to the platen car- 75 riage, at the same time having one finger of the same hand available to actuate the line spacing lever 14.

In order that the auxiliary carriage may be readily shifted along the platen carriage to different predetermined selected positions, so that a vertical columnar field on the bill sheet may be brought successively to overlie difierent columnar fields on the ledger sheet, I have provided simple key controlled means that may be readily actuated to attain the ends specified and which will now be described.

Secured by screws 84 to the rear of the supporting bar 24, and spaced apart therefrom by washers 85, is a stop or locking bar 88 which extends throughout the length of the supporting bar. The upper edge of this stop bar is provided with looking notches 81 at intervals throughout the length thereof. Cooperating with the stop bar is a stop or locking member 88 carried at one end of a lever 89 pivoted at 9|) to the side plate ill of the auxiliary carriage. This lever extends forward and carries an oil-set key 9| at its forward end, said key being located adjacent to the finger piece 83, so that the finger piece 9| may be manipulated by the same hand of the operator that grasps the finger piece 83 and operates the key 88. A contractile spring 82 is connected at one end to a pin 93 on the end plate l8 and at its other end to a pin 84 on the lever 89. The width of each notch 81 in the locking bar is such that the locking device 88 may seat itself therein, and when thus seated will hold the auxiliary carriage against movement along the platen carriage. A depression of the key 9| withdraws the locking device 88 from a notch 81 and after a slight shifting movement of the auxiliary carriage along the supporting bar has been effected the operator may release the key 9! and the locking device will bear on the, upper edge portion 95 of the locking bar intermediate the notches 81 therein. When the auxiliary carriage has been moved far enough to bring the locking device 88 into register with the next notch 81 said device will be spring pressed into said notch and lock the auxiliary carriage against movement on the platen carriage. The operator then proceeds with the writing, the platen carriage and auxiliary carriage being locked to move together in the step-by-step letter space movements of the former.

of course any desired notches 81 may be skipped over by the operator maintaining the finger key 9| depressed until about the time the auxiliary carriage has reached the desired position where the bill sheet has overlapped and registered with the proper column on the ledger sheet where entry is to be made. The key 9| may then be released by the operator and when exact registration has been effected the locking device 88 will be iorced by its spring in the registering notch 81.

I have provided simple and 'eflective visual indicating means so that the operator may know at all times what position the auxiliary carriage is in with reference to the platen carriage and the ledger sh et carried thereby. This is quite important inasmuch as the carbon sheet C may entirely cover the ledger sheet and the operator in the absence of the indicating means would not know the exact widthwlse relation between a bill sheet and the ledger sheet. I will now describe the indicating means referred to.

The front face of the supporting bar 24 is grooved at 96 throughout its length to receive a thin sheet metal sheath 91 open at the front thereof where it has overlapping edges 08, so as to retain and expose an indicating strip or scale 90. This strip may be covered with a transparent celluloid strip I00, both of the strips 90 and I being removable endwise from the sheath 0'! when the bar 24 is detached from the end plates I3. The indices on the indicating strip preferably correspond to the headings of the different columns on the ledger sheet and to the location thereof. This indicating strip may be conveniently provided by cutting a transverse strip including the column designations from a ledger sheet and inserting it in place in the sheath 91.

Coacting with the indices on the indicating l5 strip 99 is a pointer or indicator IOI (Fig. 2)

which is fixed to and projects to the left from the side plate III of the auxiliary carriage and coacts with the indices on the indicating strip to designate the columnar position of the auxiliary carriage and the bill sheet B carried thereby with reference to the platen carriage and the different columns on the ledger sheet carried thereby. For example, when the pointer is just to the right of the left-hand dividing line of the column bearing the designation City" on the index strip, then the auxiliary carriage will be positioned relatively to the platen carriage so as to hold the bill sheet in register with the City" column d on the ledger sheet. In this manner a manifold copy of the item written on the bill sheet at this time will be produced in the proper column on the ledger sheet. of course it will be understood that when the auxiliary carriage is thus hand positioned with the aid of the indicating devices referred to, the locking device 88 will be forced by its spring into a registering locking notch 01 and lock the auxiliary carriage to travel with the platen carriage in the step-by-step letter space movements of the latter as the writing is being produced.

In the construction as thus far described it is necessary to cut the notches 81 in the locking bar to accord with the particular form of ledger sheet employed in each instance. However, inas- 45 much as one concern usually employs only one and the same character ledger sheet this special cutting of the locking bar is usually found sufficient. Nevertheless, in Figs. 6, 7 and 8 I have shown a modified form of locking bar construction,

50 or means employed in conjunction therewith, for enabling variations in the set-up to be effected to bring different notches 81 into use as may be desired. Said construction will now be described.

The locking bar 06 is, or may be, the same as 55 previously described with looking notches 81 therein at intervals throughout its length. A socalled shielding bar I 02 is mounted on and arranged parallel with the locking bar by headed Pins I03, the stems of which pass through hori- 60 zontal slots I04 in the shielding bar and are secured to the locking bar. The bar I02 may therefore be shifted or adjusted longitudinally to any one of several given positions, three such positions being provided for in the present instance.

63 The bar I02 is locked or held in any one of said three positions by a detent I05 mounted on the free end of a leaf spring-I06 secured at its opposite end by screws I0I to the locking bar 06. The detent is held under spring pressure in any one of the three locking notches I08 in the bottom edge of the bar I02. The upper edge of the bar I02 is provided with notches I09 at different points along its length. The adjustment of the bar I02 will vary the notches 81 and I09 which are brought into register, three diiferent adjustments of the bar I02 being shown in Figs. 6, '7 and 8, providing three setups where notches 01 and I09 are in register. In Fig. 6 the first, third and fifth notches 81 (counting from the left) are exposed for the entry of the locking member 08. In Fig. 'I the first, second, fourth and sixth notches B1 are thus exposed. In Fig. 8 the first andthird notches 81 are thus exposed.

Of course it will be understood that when a full unnotched portion of the shielding bar I02 overlaps a notch 81 in the locking bar, said bar I02 will prevent the entry of the locking device 00 in the covered notch 81 thereby rendering it ineffective.

By these means a variation in the set-up of the locking means for the auxiliary carriage may be readily brought about without changing the locking bar.

In order that ready access may be had to the platen at both front and rear thereof for the ready introduction, adjustment and removal of the work sheets and more particularly the ledger sheet L and carbon sheet C, I provide a construction that enables the auxiliary carriage to be shifted from its normal position over the platen, as shown in full lines in Fig. 1, to an unobstructing position, indicated by the dotted line showing in the same view and also that enables the auxiliary structure as a whole to be applied to or detached from the machine.

Such construction involves the pivoting of the downwardly and forwardly projecting arms N0 of the end plates I3 of the supporting frame to the front of the platen carriage. Preferably this is effected in such a manner that the supporting frame with the auxiliary carriage and all of the remaining parts carried thereby may be detached from the machine, so that this entire auxiliary structure may be applied to or detached from the platen carriage as a single unit and in the nature of an attachment that may be applied to a standard machine.

A convenient manner of pivoting the supporting frame on the platen carriage is to provide a bearing opening in the end of each arm H0 to receive the usual rock shaft I I I by which the feed rollers I0 are controlled. This provides for swinging the supporting frame and the parts carried thereby from the full to the dotted line positions in Fig. 1 and vice versa, the weight of the parts maintaining the supporting frame in its full line position with the feed rollers II pressed by such weight against the platen and limiting the downward motion of the supporting frame.

In order to firmly connect the supporting frame at the rear thereof to'the platen carriage and resist any side strain on said supporting frame I provide means which will now be described.

Each end plate I 3 of the supporting frame is provided with a depending rearwardly extending arm H2 which at its lower end is received and guided between oppositely inclined faces II! (Fig. 5) on collars Ill. Each collar is secured by a set screw I IS on the usual cross bar or cross rod H6 that unites the end plates I" of the platen carriage. The cam face H3 on each collar III joins a vertically disposed face 8. The distance between the parallel faces H8 on the two companion collars is about equal to the thickness of the lower end of the associated arm 2, so that said arm when in normal position is held snugly between such parallel faces and resists any lateral strain on the supporting frame at the rear side thereof. It will be observed from Figs. 1 and 5 that the lower end of each arm II2, when in normal position, does not reach contact with the cross rod I I6 and does not interfere with the weight of the supporting frame and the parts carried thereby applying the feed rollers II to the platen.

Means are employed to limit the movement of the supporting frame to the dotted line position in Fig. 1. In the present instance such means comprise a pair of links 9 and I20 pivotally 10 united at their adjacent overlapping ends, as inof the bill or the work to be done.

dicated at I2I. The rear link H9 is pivoted at its lower end on the cross rod II6, whereas the lower end of the forward link I20 is pivoted on the cross rod I2 of the supporting frame, and on which the feed rollers II are mounted. A stop pin I22 on the link I20 coacts with a projecting end I23 on the link I I 9 to limit the relative movement of the links as they approach a straight line position, as indicated in dotted. lines in Fig. 1. This prevents a dead centering of said links, and prevents a locking of the supporting frame in the dotted line position at the same time supporting! it in such position and limiting its motion in this direction and holding the parts carried thereby out of contact with the machine frame and parts carried thereby.

It will be understood that by carrying the lower end of the bill sheet B in the unobstructed channel 9 between the deflectors I and 8 it is held free from interference with its displacement with the auxiliary carriage along the platen carriage.

It is thought that the operation of the machine will be fully understood from the foregoing description it being understood that an independent line spacing advance of the bill sheet is effected after the entry of every item thereon, whereas the manifold copies of such items are distributed in different columns along a single horizontal line on the ledger sheet.

While the shifting of the auxiliary carriage on the platen carriage, the line spacing of the bill sheet, etc., are entirely hand controlled, such operations may, nevertheless, be rapidly and accurately effected.

The bill sheet B shown in the present instance is a multiple form sheet comprising, say, four corresponding printed leaves or forms I24 united at adjacent edges I25 and having interleaved carbon sheets I26 disposed between the bill forms I24. The spaces for the entry of data on the various forms I24 of a multiple bill sheet are maintained in register so that an item entered in a given space on the first or outermost leaf will be duplicated as a manifold copy in a corresponding space on each of the other leaves, thus giving four copies of a bill at a single writing in addition to corresponding entries on the ledger sheet.

I have not gone extensively into the detailed manner of filling in each item on the bill and ledger sheets in the foregoing description as this varies widely depending on the character In some instances part of the data is filled in on other machines and in some instances items are sub- "sequently filled in with pen and ink on the vwritten bills. However, the single example given, and the description of the use of the machine in connection therewith is sufllcient to arrive at a clear understanding of one of the various uses to which the machine may be put.

The machine of the present invention has proved highly eflicient in various fields in which it. has been employed, and has proved highly effective, rapid and accurate in operation in use in connection with highly complicated tax bill entries of different kinds. It may be mentioned in this connection that with each machine of the present invention from 1200 to 1500 bills and extensions per day may be readily made; that in a very brief time operators acquire such speed and that the machines give no trouble and have proved highly satisfactory from every point of view.

Although I have described in detail one form or embodiment of my invention it should be undlrstood that various changes may be made in the construction, and that parts thereof may be employed without others, without departing from my invention as it is defined in the accompanying claims.
